Hi, Folks.
3 X Cat 60s GRUNTING.



Just my 0.02.

Love to hear those 60's!!!!

thats my idea of a tractor pull. and a real demo of what these old girls actually did.

Those high torque - slow speed engines --- PLAIN COUNTRY MUSIC - at night you could see the red manifolds and blue fire from the stack.
Sixty , Seventy Five, Thirty all have sounds of their own. Then came the Early Diesels - Thirty Five - Forty, Fifty, etc that made music of their own too.
I operated a Sno-Go that had a Climax K gasoline engine - goverened rpm, no load was 1100 but put a load on it and it would BARK!
So many engines of different manufacture, and most were identifyable by the sound they produced. (only if one payed attention)
Thanks for the video -
CTS
